Rivos is a Santa Clara-based silicon startup founded in 2021 that designs data-center class GPUs and AI accelerators around the open RISC-V instruction set architecture, fabricated on TSMC's 3nm process. The company is also developing a CUDA-to-RISC-V translation layer to ease migration of Nvidia-based AI workloads onto its silicon. Rivos raised a 250 million dollar Series A in 2024 led by Matrix Capital Management with Walden Catalyst and Dell Capital Partners, followed by additional rounds bringing total funding above 370 million dollars at a valuation north of 2 billion dollars. In October 2025 Meta announced an agreement to acquire Rivos to bolster its in-house custom silicon program. The company has operated in near-stealth mode and currently exposes no public website content, SDKs, or APIs, so this profile is intentionally an empty apis list with external press and acquisition references.
